# Understand and Configure Player Rankings

> Learn how Match Point calculates Elo-based ratings, how wins and losses affect points, and how to view and filter leaderboards by sport or division.

Match Point uses an Elo-based rating system to rank players across sports and divisions. Every completed match updates the ratings of the participants based on the result and the relative strength of each opponent. Higher-rated players gain fewer points for beating lower-rated opponents, while upsets produce larger swings. This keeps the leaderboard competitive and responsive to actual performance.

## How the Ranking System Works

Each player starts with a default baseline rating, or an admin-assigned initial rating if one was set during profile creation. After every completed match, Match Point recalculates both players' ratings using the standard Elo formula. The size of the change depends on three factors:

* **Result**: wins add points, losses subtract points
* **Opponent rating**: beating a stronger opponent yields a larger gain
* **K-factor**: a sensitivity constant that controls how quickly ratings respond to new results

Rankings are organized into categories per sport, so a player's tennis rating and pickleball rating are tracked independently. Within each sport, you can also split rankings by division or skill tier.

## View the Rankings Leaderboard

Open the **Rankings** page from the main navigation to see the current leaderboard. The default view shows all active players sorted by rating within your club's primary sport. Use the filters at the top to narrow the list:

* **Sport**: switch between tennis, pickleball, badminton, or any other sport configured for your club
* **Division**: limit results to a specific competitive tier or league
* **Time range**: view all-time ratings or only results from the last month, quarter, or season

## Filter and Search Rankings

Use the search bar to find a specific player by name. Combine filters to answer questions like "Who is the top-rated doubles player in Division B this quarter?" The leaderboard updates in real time as match results are entered.

## Manually Adjust a Player's Rating

Admins can override a player's calculated rating when needed, such as when a strong player transfers in from another club. Open the player's profile, click **Edit**, and change the rating field. The new value takes effect immediately and will be used as the baseline for the next match calculation.

<Note>
  Ratings only update from **Completed** matches. Matches that are scheduled, in progress, or cancelled do not affect player ratings. Make sure to mark match results promptly so the leaderboard stays current.
